How to design risk-based regression testing for transaction-critical systems where random test repetition is not enough.
What makes a system critical
Defects can affect revenue, payments, records, operations or customer trust.
Risk-based planning
High-impact flows, recent changes, fragile areas and integrations deserve stronger coverage than stable low-risk screens.
Automation priorities
Stable high-value API, data and transaction flows should be protected before broad UI repetition.
Release confidence
A useful suite communicates what passed, what changed, what risk remains and what evidence supports release readiness.
